Detectives investigating whether mosque arsonist had help

FORT LAUDERDALE, Fla. – Authorities are investigating whether a man accused of torching a Florida mosque was part of a conspiracy.

Lt. Adam Goodner of the St. Lucie County Sheriff's Office said in an email Friday that detectives are investigating who Joseph Schreiber spoke to on his cellphone moments before the fire was set Sunday night. Detectives said in their arrest affidavit that surveillance cameras at the mosque, which was once attended by Orlando nightclub shooter Omar Mateen, caught the arsonist on his cellphone.

Former inmate Ralph Alfonso served prison time with the 32-year-old Schreiber. He told The Associated Press he doesn't think Schreiber is intellectually capable of plotting the blaze and must have been put up to it. He says Schreiber is easily led.
